摘    要:本文针对历年来某条埋地管道腐蚀速率变化较大的特点,运用具有适用性广,预测准确率高等优点的灰色系统预测模型及灰色GM(1,1)模型对其腐蚀速率进行预测,并对模型精度进行了分析和检验。建立的GM(1,1)模型经拟合精度检验(C=0.1340,P=1.00),模型判为优,预测精度高,能达到预测要求。最后,验证了灰色GM(1,1)模型用于埋地管道腐蚀趋势的可行性及有效性。

关 键 词:埋地金属管道  灰色系统GM(1  1)模型  腐蚀速率预测

Abstract:In this paper, over the years of a buried pipeline corrosion rate changing largely is studied. Grey prediction model and grey GM (1,1) mode is widely applied to predict the corrosion rate and the accuracy of the model is analysis and tested. The establishment of the GM (1,1) model fitting accuracy of the test (C = 0.1340, P = 1.00), model is good, high-precision, and achieve forecast demand. Finally, the verification of the grey GM (1,1) model for the buffed pipeline corrosion trend is feasibility and effectiveness.
Keywords:buffed metal pipeline  grey system  GM (1  1) Model  corrosion rate forecasting
